Hanna Marine dKH Alkalinity Checker® HC - HI772

http://hannainst.com/hi772
The Hanna Marine Alkalinity Checker® HC - HI772 (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure alkalinity in degrees of calcium hardness (dKH). Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results.
